There are 3 ports involved. The 0xed "non-existant delay port" and a pair
of ports that are through the Super-I/O / IDE. They are used in a
index+value setup similar to reading/writing the AT keyboard controller.

Note the winbond docs are incomplete for the W83627HF at least.

Give us a shout if you need any docs/programming help.
